💅 nal_h264_matrix_coeffs(9) 💅

okay bestie, welcome to the Kernel API Manual page for nal_h264_matrix_coeffs 🎀 like yes the title is also the function name, we been knew, but let's get into it ✨

🌸 NAME 🌸

nal_h264_matrix_coeffs — ok so this one gets you the matrix_coefficients for a v4l2 v4l2_ycbcr_encoding, and honestly? iconic behaviour 💖

🦋 SYNOPSIS 🦋

int nal_h264_matrix_coeffs (enum v4l2_colorspace colorspace , enum
       v4l2_ycbcr_encoding ycbcr_encoding );

like that's it, that's the whole signature, no cap 🫶

✨ ARGUMENTS ✨

  • colorspace — the color space, as an enum v4l2_colorspace 🌈 she's bringing the vibes
  • ycbcr_encoding — the ycbcr encoding, as an enum v4l2_ycbcr_encoding 💜 this is the one getting converted, main character energy fr

👑 DESCRIPTION 👑

ok so the whole gig here: this function converts the enum v4l2_ycbcr_encoding into matrix_coefficients, exactly as specified in Rec. ITU-T H.264 (04/2017) E.2.1 📚✨

that's the spec, that's the section, don't @ me, it's literally written down 😌

🔥 RETURN 🔥

she returns the matrix_coefficients value for the encoding you passed in 💫 that's it, that's the return, slay 🎀

like the whole nal_h264 friend group, they all ate tbh 🍓

and that's the page bestie!! 🧚 this lil masterpiece is brought to you by ./drivers/media/platform/alleg... and it's stamped October 2026, with the page being nal_h264_matrix_coeffs(9) ofc 💅 go forth and convert those enums, periodt 🌈⭐
